Claudio Modini, the hospital emergency room chief, said doctors had tried to resuscitate Gandolfini for 40 minutes at the hospital before he was pronounced dead.

An outpouring of tributes followed news of Gandolfini's death. Edie Falco, who played Tony Soprano's wife, Carmela, on the "The Sopranos," said, "I am shocked and devastated by Jim's passing,. He was a man of tremendous depth and sensitivity, with a kindness and generosity beyond words."
